Firewall rule: Allow TCP/UDP on ports
5060 and 5061 for all SIP signaling IPs in both directions.RTP Media
Allow UDP traffic from these IPs for the audio media stream. RTP carries the actual voice packets during a live call. India| IP Address | Protocol | Port Range | Direction |
|---|---|---|---|
3.110.99.6 | UDP | 5000–65535 | Inbound + Outbound |
65.1.145.87 | UDP | 5000–65535 | Inbound + Outbound |

Callbacks
Vobiz sends webhook callbacks from these IP addresses to your server. Allow inbound HTTPS traffic from these IPs so your application receives call status, hangup, and recording events. India| IP Address | Protocol | Port | Direction |
|---|---|---|---|
15.206.6.156 | HTTPS | 443 (80 for HTTP) | Inbound to your server |
35.154.59.246 | HTTPS | 443 (80 for HTTP) | Inbound to your server |
15.207.8.226 | HTTPS | 443 (80 for HTTP) | Inbound to your server |
Firewall rule: Allow inbound TCP port
443 (HTTPS) from all three IPs to your callback server. Port 80 only if you use plain HTTP callbacks.Protocol Whitelisting
In addition to IP addresses, ensure your firewall and ISP do not block the following protocols.| Protocol | Port | Use |
|---|---|---|
| SIP | 5060 / 5061 | Call signaling (setup & teardown) |
| RTP | 5000–65535 UDP | Voice media streaming |
| HTTPS | 443 TCP | Callback / webhook delivery |
| WSS | 443 TCP | WebSocket streaming (XML Stream) |
